Preface
The present title Microbiology and Biochemistry is an
authoritative text book compilated for under-graduate and
post-graduate students of various Indian Universities offering
this subject. It would· be equally useful as a text in courses
in molecular biolo,gy, pharmacology and certain other
desciplines of biology. All kinds ofmicroorganisms have been
touched to create an impression about the divl!rsity. The
scope and practices of using different micro-orgabisms have
been shown which may attract future generation. The
enormous prospect of application of microbiology and
biochemistry have been indicated
The author expresses his thanks to all those friends,
colleagues, and research scholars whose continuous
inspirations have initiated him to bring this title.
The author wishes to thank the Manglam Publications,
printer and staff mambers for bringing out this book.
Constructive criticisms and suggestions for iniprovement
of the book will be thankfully acknowledged.
